Scheduled Maintenance Guide ENGINE IDLE HOUR METER (IF EQUIPPED): Your vehicle may be equipped with an idle meter to indicate how much time the vehicle is idling in P (Park) or N (Neutral). The meter is incorporated with the vehicle odometer. Depressing the odometer-reset button once will display the trip odometer (miles [km] followed by a "T" for trip odometer); depressing the odometer-reset button a second time will display the idle meter (hours followed by an "H" for hours). The idle meter only accumulates time when the vehicle is in P (Park) or N (Neutral). Displayed time is cumulative for the vehicle. It cannot be reset to zero. Police/Fleet vehicles often experience long periods of idling, during which engine oil will continue to break down but distance is not accumulated on the odometer. To assist fleet managers in maintaining proper oil change intervals, the idle meter will help determine when an oil change is required. For every hour that the vehicle idles, it has accumulated the equivalent of approximately 33 miles (53 km) of driving. Using the combination of the vehicle odometer and idle meter allows the fleet manager to better determine when the oil needs to be changed Engine idle hour meter calculation: Idle hours x 33 = miles (km) equivalency Miles (km) driven + miles (km) equivalency = oil change interval Example: When the odometer has accumulated 3,000 miles (4,800 km) and the idle meter shows 61 hours, a 5,000 mile (8,000 km) oil change interval will have been reached: 3,000 road miles (4,800 road km) + (61 idle hours x 33 miles [53 km]/idle hour) = 5,013 miles (8,067 km). 295 2011 Town Car (tow) Owners Guide, 2nd Printing USA (fus)
